WITNESSES ATTORNEY TEST APPARATUS FOR RADIATOR-SECTIONS.

Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed April 22, 1914. Serial No.- 833,600.

To all whom it may concern.

Be it known that I, Jonson A. Goonnioir, a citiz'fi of theUnited States. residing at Huntingdon, in the county of'Huntingdon and State of Pennsylvania, have invented a certain new and useful T est Apparatus for Radiator-Sections, of which the following is a specification.

The purpose of my invention is to pro-- ride 'rotatable radiator testing heads with pear in the specification and claims hereof.-

While recognizing that my invention might be applied in many forms, I have preferred to illustrate it by but two forms thereof, both of which have proved to be simple, effective and inexpensive and which at the same time well illustrate the principles involved.

Figure 1 IS a side elevation of mechanism embodying my invention. Fig. 2 1s a top plan view of the right hand clamping head in Fig. 1. Fig. 3 is a partial-section of ,Fig. 1 corresponding to line 3 Fig. 4 is a broken side elevation, showing a second form.

a of Fi 2.

fEa ch radiator section has a boss on each ,side near each end, where the section s to fitfla'gainst the next section of'the radiator.

The openings for admission of heating fluid are formed in the .middle of these bosses.

For hot water radiators these openings are placed at opposlte sides of the same end; for

steam, at oppositeends. Ine'ither event the section is ordinarily tested before the bosses I have been machined by forcing water into the section through. one of these openings at considerable pressure, while the other opening or openings are sealed. Faults are disclosed by the leaks which occur.. Rotation of the testingjapparatus while the test is being made is desirable to permit fallinspec'tion of the section being tested and Si-milan numerals of reference indicate like parts.

1 quick and convenient reliable clamping and release of the sectlons successively tested is of great importance. lVhere the inlet and outlet'openings in the section occur at one end only, one of the test heads performs supporting functions only.-

The radiator section 5 is provided with bosses 6, 7 and 8, 9 upon opposite sides in each pairand with the pairsat opposite ends. Two at least of these faces are apertured to permit flow of heating fluid into and out of the section. If the apertures be 'at one end only this end is intended to be at the right in Fig. 1.

The section 5 is placed in rotatable test heads 10, 11, of general yoke or C-clamp form, with the bosses 6, 8 resting upon sealing gaskets 12, 13. preferably rubber, covering the faces 1- 15 of the lower jaws 16, 17, comprising the relatively fixed jaws of the clamps. The heads are spaced suitably to accommodate the length of sections being tested and are rotatably mounted. The upper aws 18, 19 complete the yokes or clamps and carry relatively movable clamping plates and quick-operating means for setting and releasing them.

he clamping plates 20, 21 are gasketed at '22, 23 to seal the upper boss faces of the section tested. The plates are extended upwardly (axially) at 2%, 25 and screwthreaded at 26, 27 to screw into the plungers 28, 29 or parts carried by them. The connection between the-plates and plungers may thus be either rigid and fixed or adjustable to take up the wear of the gaskets or accon'nnodate different thicknesses of section, as may best, suit the wishes or needs of the user.

I prefer to interpose cushions between the upward extensions of the plates at 9A and "25 and the plunger-s 28, 29 without losing the adjustability by the threads 26 and 27 and, for this purpose. thread the extensions EZ-l,

25 into heads 30, 31 slid able within the and are lowered and raised to set and release the clamps by quick operating lever mechanism, one, form of which, shown in the first threehfigures, comprises toggles made up of links 35, 36 and levers 37, 38 operated by handles .39, 4L0. The'links are pivotally connected'tothe' plungers'at one end and to the 'le've1=s atf-the other, and the upper ends of the levers are pivoted in brackets 41, at) rigid with" the jaws 10, 11..

.The gasketsnare secured to-the faces 1-1,

and 21 by means of screws 43. The

gasket 13, however, is-securedto the face 15 .by a nipple 4A which allows. fluid under pressure to pass into the-radiator section from passage 45. \Vater isordinarily used for abet-est and is supplied under pressure through a pipe 46 whicli'enters the head Within recess 17 and is flanged or provided witha collar therein at 48. v The outer part of the recess is interiorly screw-threaded at a 49 to rece'ivea stufling box 50 by which the packing 51 is set against the flange 48.

Inlet ofwater to the passage and radiator section. is permitted or checked by valve 52 and the pressure is relieved after test through valve'53.

The heads 10 and 11 are made rotatable by stub-shaft extensions 54: and 55 in the direction of the length of the spindle, these shafts havingbearing in the pillows 56, 57

and being prevented from movement in either direction by the shoulders 58, 59 and the collars 60, 61, secured to the shaft in any suitable manner. The recess 4?? is formed witgin the stub shaft 55 and is coaxial therewit For the. purpose of illustrating that the substantially parallel movement of levers is IIOt'COIIfiIIGd to the link construction, I have shown one other of the many other such means in Fig. 4 where the brackets 462 carry cam levers having handles 40 and cam gI'OOVQS'GQ within which pins 63 are fitted. The pins are supported in the ears 61 connected with theplungers. I aim to make the slope-of the cam gradual enough for it.

to hold theparts in their positions with the pins at any point along the length of the cam grooves, which, in connection with the cushions within the plungers, gives a much greater range of usefulness than when the lever must be thrown to the same position at all times. lVear and-(.leterioration of the gaskets as well as deviation in the thickness of the sections between opposite boss faces are both compensated for by the range of movement of the cam and the movement of the parts within the plungers.

In operation, the valve is closed at the time a section is to be inserted for test. The operating handles are at their greatest 'distance away from each other and the plun gers are lifted. The section to be tested is' rested upon the gaskets by which the surfaces-of the metal of the lower jaws are faced, and which provide sealing faces. During this operation the heads 10 and 11 closed, the valve 52 is now opened, admitting'water to the section under test and the heads are oscillated or rotated to permitfull examination of the section. ,Theyare then turned back-to place, the valve 52 closed and the valve 53 openedto release the water used. The handles are; then moved away from each other to release the movable clamping plates and permit the removal of the section tested and insertion of a new section. I

.It will be evident that the preferred movement of the operating handles toward and away from each other, in the operation of the clamps simultaneously, lessens the effort required and adds greatly to the convenience in operation.

movement might be used with the rotatable heads shown and that various changes It will be further evident that other forms of rapidclamp might be made in the construction invented by me without departing from the spirit and scope of my invention.

.Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
